Spinneret plate

Abstract

The invention provides a spinneret plate which comprises a spinneret plate body and spinneret orifices distributed on the spinneret plate body. Each spinneret orifice is composed of 3-5 spinneret inner holes, the spinneret inner holes are triangular holes or trilobal holes, spinneret inner hole base angles of each spinneret hole are arranged on the same line, and a distance between two spinneret inner hole base angles of each spinneret orifice is 0.001-0.01 mm. Profiled fiber produced through the spinneret plate has the advantages of triangular fiber and cross fiber simultaneously. The produced profiled fiber is large in degree of profile, and fabric has various performance advances of being full in color, bright in gloss, good in fluffiness, moisture absorption, elasticity and feel and the like.

Description

technical field [0001] The invention relates to the field of fiber forming equipment, in particular to a spinneret. [0002] Background technique [0003] Synthetic fibers are usually round fibers with a solid structure inside, so their hygroscopicity and dyeability are poor, and when light hits the surface, it is easy to form diffuse reflection and poor gloss. Therefore, the comfort of the fabric is often not good, and it is difficult to satisfy the needs of modern people. [0004] Shaped fiber is the fiber obtained after the cross-section is shaped. This fiber can endow the fabric with a variety of performance advantages, so it is widely used. The production and processing process of common special-shaped fibers in synthetic fibers is to open a number of spinneret holes with cross-sections corresponding to the cross-sections of fibers on the spinneret, and spray the spinning melt from the special-shaped spinneret holes on the spinneret. After cooling and solidification,...

Problems solved by technology

[0005] At present, there are many cross-sections of special-shaped fibers that have been industrialized, such as triangular, trilobal, pentagonal, cross-shaped, flat, C-shaped, H-shaped and cross-shaped fibers, etc., but most of the special-shaped fibers currently produced have only a single and the same Therefore, it is difficult to perform multiple functions at the same time. For example, although the triangular, trilobal, and pentagonal fibers have the function of small prisms, they can split the natural light and recombine them, giving off a silky luster and giving people a special feeling, but they are hygroscopic. The moisture conduction performance is very poor; although the flat fiber has a good gloss effect, its moisture absorption and moisture conduction performance is also poor; and the C-shaped, H-shaped, and cross-shaped fibers, the capillary structure produced by the groove structure on the surface Phenomena can have good moisture wicking effects, but relatively poor gloss
